Large open source software projects often have a globally distributed development team. Studies have shown developer turnover has a significant impact on the project success. Frequent developer turnover may lead to loss of productivity due to lacking relevant knowledge and spending extra time learning how projects work. Thus, lots of attention has been paid to which factors are related to developer...
Software development remains a predominantly male activity, despite coordinated efforts from research, industry, and policy makers. This gender imbalance is most visible in social programming, on platforms such as Stack Overflow.To better understand the reasons behind this disparity, and off er support for (corrective) decision making, we and others have been engaged in large-scale empirical studies...
Deduplication technology has been increasingly used to reduce the primary storage cost. In practice, it often causes additional on-disk fragmentation that impairs the reading performance. Existing deduplication algorithms mainly focus on the static data layout design so that the random I/O requests are largely avoided and the harmful effect can be alleviated. However, our trace-driven emulations show...
Traditional smart card patch is processed in the place where main command accepts. This patching method has the shortcomings of low efficiency and long time to execute. The paper proposes a new mechanism for patching ROM smart card APDU commands. The user can patch instructions for APDU commands according to their needs and redesigned APDU commands. It will go to the new designed instruction to execute...
Deduplication technology has been increasingly used to reduce the storage cost. In practice, it often causes additional on-disk fragments that impair the reading performance. To reduce the impact of fragments, traditional thought of defragmentation that reallocating files on-disk to achieve contiguous layout has been widely used in many operating systems. Unfortunately, file defragmentation is highly...
